HALF OF HIS RIGHT TO CHARLES M. ADAMS, OF SAME PLACE.

HEEL-TRIMMER.

SPECIFICATION forming part of Letters Patent No. 233,108, dated October12, 1880.

Application filed J nly 22, 1880.

To all whom it may concern Be it known that I, FRANKLIN MoUL'roN,citizen of the United States, residing at Ashland, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Heel-Trimming Attachments; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, and to the letters and figures of reference markedthereon.

This invention consists in a device for attachment to heel-trimmers forthe purpose of trimmin gorevenin g the soles of boots and shoes next tothe uppers.

In the drawings, Figure 1 represents aheeltrimmer with my sole-eveningdevice applied thereto. Fig. -2 is a detail view of theheeltrimming-knife gage and the device for trimmin g or evening thesole. Fig. 3 is a vertical section, showing the heel and'edge of thesole in the act of being trimmed. Fig. 4 shows, in detail, my improvedsole-edge trimmer with gage-plate for regulating its extent of cut.

A represents one oftheusual forms of heeltrimming devices, where onenon-rotatable straight or concave knife is used. B is the knife fortrimming the outer side of the heel.

0 represents my improved device, which is .attached, by means of ascrew, a, passing through the slot 0, to the frame of the heeltrimmer,in front of and inside of the heeltrimming knife, where it is heldfirmly by a nut, b, on the other side. This device, as shown in Fig. 4,has a shoulder or step, d, to adapt it to fit the under side of theframe, said shoulder terminating at its lower part, on one side, in aknife, D, whose office it is to cut away and take out the single shavingwhich hangs over the counter of the boot, which operation is performedat the same time that .the heel is trimmed, as shown in Fig. 3, themovement forward of the heel-trimmer at the same time carrying forwardthe thereto-attached knife D, so that the two operations of trimming theheel and evening the sole-edge and removing therefrom the strip ofleather protruding therefrom (No model.)

are accomplished at one movement of the machine.

The shouldered or enlarged portion of the attachment is recessed at cfor the reception of a gage-plate, E, which is firmly secured therein bya screw or other suitable means, f, for the purpose of regulating theextent of cut of the knife D.

S represents the cutting or shaving as it is being removed from the edgeof the sole by the movement forward of the knife D.

Heretofore the practice has been to remove the strip hanging over thecounter by hand, either before or after the heel is trimmed; but by theuse of this sole-evening device this strip may be readily removed andthe edge of the sole trimmed or evened at the same time and during themovement forward of the heel-trimmer, to which the device is attached,thereby saving fully one-third of the labor usually expended upontrimming the edge of the sole next the upper, while at the same timeaccomplishin g this result in a more perfect and reliable manner thanwhere the operation is performed by hand.

The device may readily be applied to heeltrimmers generally whererotatable knives or burr-wheels are not used, as no alteration of themachine is required to adapt it to receive the attachment, the form ofwhich allows it to be readily secured to the framing or arm immediatelyforward of the heel-trimming knife, as heretofore explained.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The sole-edge trimmer herein described, consistin g of the shoulderedand recessed plate 0, knife D, and gage E, substantially as and for thepurpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

FRANKLIN MOULTON.
